KING OF PRUSSIA, Pa., Feb. 21, 2013 /PRNewswire/ --CSL Behring today
announced that the United States Food and Drug Administration has approved a
40 g (400 mL) vial size for Privigen®,  immune globulin intravenous [human].
The new vial size will simplify preparation and administration of the product
when high volumes of it are required. Privigen is approved for the treatment
of patients with primary immunodeficiency (PID), a group of rare and serious
diseases of the immune system, and provides effective protection against
infection by assisting the body in maintaining a normal level of
immunoglobulin. Privigen is also approved in the United States for chronic
immune thrombocytopenic purpura (ITP) to raise platelet counts. With the
addition of the 40 g vial, Privigen will be available in four sizes in the
United States, including 5 g (50 mL), 10 g (100 mL) and 20 g (200 mL). The
first supply of Privigen in this new vial size will be introduced in June.

"CSL Behring strives to bring new innovations to the healthcare marketplace
and deliver products that enhance the patient experience," said Val Romberg,
Senior Vice President, Research and Development. "The 40 gram vial size for
Privigen continues that commitment by reducing the complexity of
administration and increasing time savings for healthcare providers."

Privigen can be administered through pooled infusion using intravenous (IV)
bags or through individual vial infusion – hung separately from the IV line.
Patients who are administered Privigen are dosed based on body weight. For
patients who require high doses of Privigen, the 40 g vial size of Privigen
will reduce the required number of individual vial infusions or the need to
pool multiple vials for an IV bag infusion.
